btrfs: simplify range end calculations in truncate_block_zero_beyond_eof()
The way zero_end is calculated and used does a -1 and +1 that
effectively cancel out, so this can be simplified. This is also
preparatory patch for using a helper for folio_pos + folio_size with the
semantics of exclusive end of the range.
